We also know A+X is part of Marvel Now. And there are solo books and some of the canned books in October are getting relaunched..On a business end its's absolutely an attempt to respond to the New 52, and attract new or otherwise disengaged comic readers.
Like DC did before, Marvel will set up several new #1 titles which will in theory serve as a good jumping on point for people of those categories.
However, there are three very different facets about how Marvel Now! will be done as opposed as to DC's attempt at a major jumping on point,the new 52.
1.Some titles will continue on due to popularity or being too fresh to relaunch. Winter solider, Daredevil,Captain Marvel,Secret Avengers, and others will not be relaunched at all.
2.Countinuity is still the same, it's just a new storytelling era (which gave me a big ol sigh of relief)
3. Not all new titles will be released on the same month. The Marvel Now! stable of books will be released between October and Febuary.
So yeah, it should be a good jumping on point, and its very expansive.
So far we know 4 titles that will be a part of the Marvel Now! initiative; Rick Remender's Uncanny Avengers featuring a team composed of members from both the X-men and Avengers, Brian Bendis' All new X-Men which is about the original 5 X-men coming to the future to discover a less than bright future, Johnathan Hickman's Avengers which we know will have an 18 member cast with the movie verse squad, Shang-chi and 11 other undisclosed characters, And Hickman's New Avengers which we know very little about.
Other titles that are ending and we can presume will be renewed are Captain America,Fantastic 4(and its sister title FF) Iron Man,and Thor(and its sister title Journey into Mystery)
There are other titles that will end but thats what sticks in my mind.
So stay tuned, and I hope that was informative!
